Developer Appliance

If you are a developer, you will be pleased to know that the PCQLinux 2008

Developer appliance packs a punch and more. You can program in the top three

programming languages/platforms in the world without requiring to install

anything new — PHP, Java and .NET.

Programming in .NET



PCQLinux 2008 allows you to work with the very popular .NET platform without
even installing Windows! With this ability, you can code for .NET projects

without requiring either Windows, .NET Framework or Visual Studio. Mono is the

application in PCQLinux that allows you to do this easily.

You can create ASP.NET 1.1 or 2.0 web applications quickly. But first you

must install the XSP ASP.NET runtime engine by issuing the following command:





yum install xsp. This will download and install a
tiny runtime engine for ASP.NET. Once installed, open up /etc/httpd/ conf/httpd.conf

and look for either of the following lines:



Include /etc/httpd/conf.d/mono.conf


Include /etc/httpd/conf.d/*.conf

If either of these two lines exist, check whether the mono.conf file does

reside in /etc/httpd/conf.d. You can now start

creating ASP. NET 1.1 or 2.0 web apps on Linux.

As a start, simply copy the directory /usr/lib/xsp/test

to /var/www/html.

Run apache using the command: service httpd start.

Once the server is started, open up Firefox and browse to http://localhost/test.

You will be greeted with a new screen that lists a large number of samples that

you can click on to view the results of in the browser. Each of these samples is

an ASP.NET Web form that runs on both Windows (using .NET) or Linux (using Mono/XSP).

You can now start creating your ASP.NET Web applications on PCQLinux as well.

Programming in PHP



PHP is an open source dynamic scripting language that is very popular in

creating websites. There are many PHP based web applications that you can

download for free from the Internet. PCQLinux 2008 Developer Appliance comes

with the core installation of PHP pre-installed. You do not need to install

anything new for running normal applications. However, PHP does have a number of

optional modules that you can download and install as well.

To test whether your PHP installation is up and running, make sure that the

web server is started using the command given in the previous section. Now open

a text editor and type in the following exactly:

A sample PHP page running on PCQLinux 2008

phpinfo();



?>

Save the file into /var/www/html as “test.php”.

Now open Firefox and browse over to http://localhost/ test.php.

You should see a full PHP page displaying a number of system values. You can

now start creating/using PHP applications on this appliance.

Programming in Eclipse



If you are a Java developer, you will find that creating Java applications using
the Eclipse RAD tool will allow you to become productive much faster and you can

create your applications much more easily.

We have included this tool in the PCQLinux 2008 Developer appliance and you

can start it up from the Programming menu.

When you do start it up, you will be prompted for a workspace to use. You can

accept the defaults if you wish. Once the application starts up, you can choose

the kind of project (enterprise, mobile, device, framework, etc.) that you wish

to work on. The tool allows for all advanced coding features like autocomplete,

refactoring, debugging and more.

You can also download a huge number of plugins for this platform from

www.eclipse.org and participate in the Eclipse community at the same location.

The tool also comes with a large number of samples that you can install to help

you get started.
